title: Molecular relaxations in magnesium polymer electrolytes via GHz broadband electrical spectroscopy.
abstract: GHz broadband electrical spectroscopy (G-BES) is adopted to investigate the molecular relaxations and interactions occurring within the system in an oxygen- and water-free atmosphere in the 300 kHz-20 GHz and -40 to 250 °C frequency and temperature ranges, respectively. A new electrolyte for magnesium secondary batteries that can transfer magnesium ions efficiently is presented. This electrolyte is based on polyethylene glycol 400 and a polymeric form of δ-MgCl2 . The information obtained by G-BES is crucial for studying the conduction mechanism of these new electrolytes.
